As Mike O'Malley previously stated, I just plugged a RCA to 1/4" cord right into the RCA jack on the expression pedal housing of my M-3 (after removing the back), ran the cord through the power cord hole, re-installed the back, plugged the 1/4" end directly into a Electro Harmonix Lester G Leslie pedal, then connected the stereo outputs of the Lester G into 2 separate Fender KXR amplifiers topped with Motion Sound Pro-3's spaced across the room from each other and holy smokes.......you've basically got panning Leslies. Electro Harmonix nailed the Leslie sound for around $200 also......I am still blown away at how easy & cheap I got my M-3 to scream even with just the Lester G right into the PA.
Mark, Thanks for posting this. Just acquired an old Hammond model G. Someone appears to have already done this modification. I’m new to owning a Hammond and not afraid to work on it. Although, I have tons of questions and the technicians here in Nashville are not very helpful
on M-3s there is an RCA jack on the expression pedal housing that says "radio input"... there is a low level signal there that I boost with a ProArt Preamp and send the 1/4 in output to my converted 147 Leslie or my Motion Sound Pro3T...
Yes. I actually took a signal from the preamp as you suggested and hooked it up to 2 Direct Boxes and the Leslie Digital Pedal. I was able simulate the sound Leslie 122 and 147 Cabinet for less than $600.
Thank for your helpful video and sorry for my ignorance: Have I to simply solder an instrument/guitar cable to the two black/red "G" terminals and plug the jack to the mixer/amp/PA system? Thanks for the kind answer you'll want to give me 🙂
hello...great video info.....Question: Have a A105....want to hook up my 122 that has both a vintage 428 and a type 3M echo unit that was on my other C3....I see how its connected to the C3 but not sure connecting it to the 105 that has the speakers in it.....I assume I connect to the 58amp, but not sure....Any help would be appreciated.....
PLZ!! I have an old X-66 with NO OUTPUT. I'm going to replace the AC Power cord first and see if that does anything. What would be next other than trash the thing?
It's audio, not electricity. If you're familiar with electricity think if it like a 240v curcuit, two different kinds of hot, and a ground, when you hook onto one hot, you get half the voltage.
yeah..maybe you make "ok" guitar amps, but you're junkin out some pretty cool stuff man. been there, done that, now have exactly one dozen Hammonds, mostly re-capped CORRECTLY, and gone thru, from a 49 M, to a 62 A-100, some modded, some not. 5 Leslies, again, some modded, some not. I am mainly a guitar and bass player, and have a bunch of amps as well.(Fender, Traynor, etc..not a Marshall fan tho) i think the purpose built amps just end up sounding better..after cappin, etc. LOOOOOOVE the Hammond sound..too cool to tear em down.imho, unless it was a real roach.
Terrible video. 7 minutes to tell someone to connect to the G and G. No explanation as to how, if there are resistors needed and why someone might need a resistor, where the resistor would go, how many......

That RCA jack was a phono input, so if you use it as an output there's a resistor that you should remove to get the full range sound.
Thanx for this info....I wondered if doing this would work!!
Mark,

On an Organ I have of this vintage, I put a Line Out from the Preamp and a Bypass Output on the Rheostat Box.

That'll work.. I vaguely remember there's a little resistor on the other side of that plug that should be taken out to get a full range signal
Thank you for this video! Helped me out tremendously in accomplishing what I needed to do on my Hammond CV.
cool, glad to have helped.

No kind answer for you
Red OR Black G terminal is + (center) of cable. Shield goes to ground.
@@richreid7098 Thank you, greetings from Italy :-)
How do you turn up the speakers that come with the organ
you can't they're not that loud, maybe 12 watts, compared to a 35-50 watt Leslie it's no match.

Plz let me know about this at dandrums81890@gmail.com THX
Had an X77 that was DOA. It actually cost me more to have somebody haul it away to the dump than I paid for it. Heavy bastard
I have a vt 100 is this the same process haven’t opened it up yet
The AO-28-5 (A-100) Has a Reverse Wired Expression Cap.
Is the cable you are using a balanced or stereo cable?
unbalanced
Does this work on a L122?
sorry, they don't have a preamp out, it's a little more complicated
I need to know how to get a line level out of mine too
look up schematics for a hammond porta-B. It is the same internals as the L-100 but has a line out jack on the back as well as leslie outs
2022 jan, interesting
Hot and cold lmao....!!!?? This ain't plumbing lol, electrical is hot and common ;-) Joking aside, thanks for the video!

wow...you should watch a video on soldering
LMAO i gut these and make AMAZING guitar amps.... this video helps me have new ideas lol

minus9us gutting these is a crime man

or why you would want to do this
Great video, thank you very much.
